Recent legislative changes in the e-notification practice within tax law establish a new framework that requires attention regarding taxpayers' obligations and notification periods. In this context, it is important to evaluate both the operation of the five-day notification rule and the new legal order shaped following the Constitutional Court's annulment decision.<\/p>\n

I. Digital Order in Legal Communication: Electronic Notification <\/strong><\/h3>\n

The delivery of official documents issued by public institutions, courts, and enforcement offices to recipients in a digital environment is an e-notification process provided through the National Electronic Notification System.<\/p>\n

Eliminating wasted time and postal expenses, this system has the same legal validity as physical notification. Operating as a notification regime independent of and prioritized over classical methods, e-notification can be used directly by the tax administration when the necessary conditions are met. The fact that the message is deemed to have been served at the end of the fifth day following its arrival at the recipient's e-notification address is of critical importance for tracking legal deadlines.<\/p>\n

 <\/p>\n

II. Start of the Period and the 5-Day Rule in Electronic Notification<\/strong><\/h3>\n

One of the most concrete steps of digitalization in tax law, the electronic notification system, while enabling the transfer of notifications from physical environments to digital platforms, has also established a new and clear legal regime regarding the tracking of legal deadlines. The \u201c5-day rule,\u201d which is at the center of this regime, is a legal presumption stipulating that the notification shall be deemed to have taken place at the end of the fifth day following the date the document reaches the recipient's electronic mailbox.<\/p>\n

Reviewing the document before five days, opening it late, or not displaying it in the system at all does not affect the legal calendar; legal deadlines continue to run. The recipient reading the document before this five-day window, reviewing it late, or not opening it in the system at all has no effect on the flow of the deadline.<\/p>\n

 <\/p>\n

III. New Era in Legislation: The e-Notification Regime After the AYM Annulment Decision and Law No. 7587<\/strong><\/h3>\n

The legal framework of e-notification, which is the cornerstone of digitalization in tax procedures, was strengthened by Law No. 7587 following the Constitutional Court's annulment decision dated January 15, 2026. The scope of obligation, exemptions, and exit conditions, which were previously determined by Ministry communiqu\u00e9s, were moved directly into the Tax Procedure Law, providing the system with a legal backbone and guaranteeing the rule that notification shall be deemed made at the end of the fifth day following the date it was delivered to the system. Thus, while strengthening the legal backbone of the system, a more definite and predictable structure has been established regarding the rights and obligations of taxpayers.<\/p>\n

 <\/p>\n

Tax Procedure Law Article 107\/A-2:<\/p>\n

\u201cElectronic notification is deemed to have been made at the end of the fifth day following the date on which the notification is delivered to the addressee through this system.\u201d<\/em><\/p>\n

 <\/p>\n

At this point, along with the amendment we specified, the fundamental principles of the e-notification system have been regulated directly at the statutory level. With this regulation, taxpayer groups required to use e-notification, exemption conditions, the principles for leaving the system, and the five-day notification presumption have been bound by statutory provisions. Thus, the legal backbone of the application has been strengthened, ensuring legal certainty.<\/p>\n

At the heart of this regulation lies a cancellation ruling by the Constitutional Court. The High Court found it unconstitutional for the boundaries of the e-notification obligation, which directly concerns fundamental rights, to be regulated by communiques issued by the Ministry of Treasury and Finance without being set by law. Therefore, rather than abolishing the e-notification system, the ruling put an end to the boundless authority granted to the administration.<\/p>\n

IV. Are Past Notifications Invalid? Transition Period and New Era in the E-Notification System<\/strong><\/h3>\n

What Will Be the Legal Status of Past Notifications Following the Constitutional Court\u2019s E-Notification Decision?<\/strong><\/h4>\n

Answer: No. Let's evaluate the legal meaning of the decision and what the new era brings together.<\/p>\n

It is not the system that is cancelled, but the way the authority is exercised:<\/strong> The Constitutional Court did not abolish the e-notification practice. It merely found it unlawful for the individuals to be mandated to use this system and the rules to be determined by administrative communiqu\u00e9s instead of laws.<\/p>\n

Past notifications do not automatically become void:<\/strong> \u201cThe approach that \u201dsince a cancellation decision has been issued, the old notifications are invalid\" is not appropriate. Each transaction is evaluated within its own period; the legislation on the date the notification was made, the legal status of the addressee at that time, and the compliance of the transaction with the procedures serve as the basis.<\/p>\n

With the new law, the system is on a more solid foundation:<\/strong> Article 107\/A of the Tax Procedure Law was amended by Law No. 7587. The scope of obligation, exemptions, and the 5-day notification period were directly codified as legal provisions, completely eliminating the uncertainty in the legislation.<\/p>\n

When these issues are evaluated together, the will of the judicial organs is not to terminate e-notifications, but rather to secure them under legal guarantee in accordance with the fundamental principles of the Constitution. Therefore, instead of concluding that past notifications will be automatically invalidated, evaluating each notification according to the rules in effect at the time it was made will prevent loss of rights. Indeed, within the framework of the amendments made to Article 107\/A of the Tax Procedure Act by Law No. 7587, as Fidelis Law and Consultancy, we are restructuring your company's obligation and exemption status, evaluating the service dates of past notifications in terms of procedure, identifying potential legal and administrative risks, and taking the necessary precautions.<\/p>\n

V. Mandatory Taxpayer Groups & Legal Exemptions <\/strong><\/h3>\n

Kurumlar vergisi m\u00fckelleflerinin yan\u0131 s\u0131ra ticari, zirai veya serbest meslek faaliyeti dolay\u0131s\u0131yla ger\u00e7ek usulde gelir vergisi beyannamesi veren t\u00fcm m\u00fckellefler e-tebligat sistemine dahil olmakla y\u00fck\u00fcml\u00fcd\u00fcr. Kanunen bu mecburiyetin d\u0131\u015f\u0131nda tutulan ki\u015filerin kendi talepleriyle sisteme kat\u0131lmas\u0131 m\u00fcmk\u00fcnd\u00fcr; %90 ve \u00fczerinde engeli bulunan m\u00fckellefler bak\u0131m\u0131ndan ise e-tebligat kullanma zorunlulu\u011fu aranmamaktad\u0131r.<\/p>\n

The revised Article 107\/A of the Tax Procedure Law has legally clarified who is obliged to enter the system. Within this framework, the operation of the system and the taxpayer groups are as follows:<\/p>\n
